The contrast between raw industrial material and polished tech is what makes it work. There's something satisfying about building things purely for yourself with no product roadmap attached, the "dildo for air bubbles" detail alone proves this wasn't designed by committee

I wonder what the practical limit is on how thin and light you can make concrete for non-structural items? I can see someone selling concrete mugs on Etsy, for example. Maybe with clever use of fillers and thin walls you could have a version of this you could actually lift. It looks great, especially in contrast to a white IKEA-style office.

People who make concrete counter tops use a lot of fibreglass fillers to get them fairly thin but if you wanted it truly light weight you’d probably need to make it out of a dense foam and coat it with something that looks like concrete.

My bathroom is a couple mm of microcement over Schluter Kerdi-Board foam, it's fairly strong. I think it can hold a laptop no problem.

I guess "I poured some concrete into a mold and put a power outlet in it" wouldn't be as eye catching of a title.

This is one of those things where someone does something incredibly simple, but dresses it up in pretty language and even some totally irrelevant chemistry equations (because they r so smrt) to make it look like more than it is. Which LLM did you paste the equation from?

And of course those who also have no idea how anything is made are unbelievably impressed. You can tell by the amount of exclamation points in all of the toxically positive reactions. Good work in that respect!

But hey, I guess it's not another vibe coded project with an LLM writeup. Progress.

Earlier quoted context omitted.

I've read that adding a little bit of graphene can make concrete much stronger, lighter and easy to shape, so would allow for thinner objects.

There are a lot of additives to concrete - the industry is large and has put a lot of money into research over the decades. You can read many many books on the pros and cons of different options.

I have not done much with concrete, but I have made lots of things out of many other materials over the years, and in general I have found that making things - and making them come out the way you want them - is never as simple as it looks. "Reality has a surprising amount of detail", it was once wisely written:

This project is not to my personal taste but I respect the work which went in to it, and I'm glad its creator got what he wanted.
